Proximity Label-MS

An interaction is inferred when a bait-enzyme fusion protein selectively modifies a vicinal protein with a diffusible reactive product, followed by affinity capture of the modified protein and identification by mass spectrometric methods.

PH domain Leucine-Rich Repeat Protein Phosphatase 1 (PHLPP1) is a tumor suppressor that directly dephosphorylates a wide array of substrates, most notably the pro-survival kinase Akt. However, little is known about the molecular mechanisms governing PHLPP1 itself. Here we report that PHLPP1 is dynamically regulated in a cell cycle-dependent manner, and deletion of PHLPP1 results in mitotic delays and increased ... [more]
